Here are the basic steps needed to get set up and contribute a patch:
We encourage everyone to contribute to Jython and that’s why we have put up this developer’s guide. If you still have questions after reviewing the material in this guide, then the Python Mentors group is available to help guide new contributors through the process. The Developer FAQ is another useful source of information.
Guide for contributing to Jython:
It is recommended that the above documents be read in the order listed. You can stop where you feel comfortable and begin contributing immediately without reading and understanding these documents all at once. If you do choose to skip around within the documentation, be aware that it is written assuming preceding documentation has been read so you may find it necessary to backtrack to fill in missing concepts and terminology.
This guide is specifically for contributing to Jython: A Python interpreter focused on good integration with the Java Virtual Machine (JVM) environment.
